Remko Popma updated LOG4J2-3214:
--------------------------------
Description:
I propose to update the text for the mitigation section of CVE-2021-44228 on
[https://logging.apache.org/log4j/2.x/security.html]
Changes: add Log4j 1.x section, and format the Log4j 2.x section as a bullet
point list for improved readability.
----
*Log4j 1.x mitigation* - Audit your logging configuration to ensure it has no
{{JMSAppender}} configured. Log4j 1.x configurations without JMSAppender are
not impacted by this vulnerability.
{*}Log4j 2.x mitigation{*}: (any one of the below will mitigate the
vulnerability)
* If possible, upgrade to the latest version: 2.15.0 or later.
* In releases from 2.7 through 2.14.1, you can modify your logging
configuration to switch off message lookups:
** use {{{}%m{nolookups{}}}} instead of just {{{}%m{}}}
** use {{{}%msg{nolookups{}}}} instead of just {{{}%msg{}}}
** use {{{}%message{nolookups{}}}} instead of just {{{}%message{}}}
* In releases >=2.10, you can:
** set system property {{log4j2.formatMsgNoLookups}} to {{true}} (see
[details|https://logging.apache.org/log4j/2.x/manual/configuration.html#SystemProperties])
** or set environment variable {{LOG4J_FORMAT_MSG_NO_LOOKUPS}} to {{true}}
(see
[details|https://logging.apache.org/log4j/2.x/manual/configuration.html#SystemProperties]).
* For releases from 2.0-beta9 to 2.7, the only mitigation is to remove the
{{JndiLookup}} class from the classpath: {{zip \-q \-d log4j\-core\-*.jar
org/apache/logging/log4j/core/lookup/JndiLookup.class}}.
